Inventor: ITO HITOSHI
IPC: H05K3/36
Filed: 1999-08-18
Abstract: PROBLEM TO BE SOLVED: To prevent a conductive connecting pin from coming off a package substrate by enabling the pin to sufficiently absorb stresses applied to the pin during the course of a heat cycle and at the mounting of the pin on the package substrate, by providing a constriction on a columnar connecting section. SOLUTION: On a columnar connecting section 102 of a pin 100, composed of the connecting section 102 and a plate-like fixing section 101, a constriction having a diameter smaller than the other part of the section 102 has is formed. When the constriction is provided on the connecting section 102, an easily bent property is given to the pin 100. When stress is applied to the pin 100, consequently the pin 100 separates comes off a package substrate 310, because the connecting section 102 absorbs the stress due to bending from the constriction. When the constriction is provided on the columnar connecting section 102 of the pin 100, therefore the pin 100 can be prevented from separating off the package substrate 310, because the pin 100 absorbs stresses applied to the pin 100 during the course of a heat cycle and at the mounting of the pin 100 on the substrate 310.

Title: Simulation system and simulator for logical circuit
Inventor: TERADA HIRONORI
IPC: G06F19/00
Filed: 1984-11-02
Abstract: PURPOSE:To achieve a higher speed of computation, by a method wherein input information of logical circuit components and a signal level are computed at each time of starting and ending the signal level and only when there are changes in the output signal level, the output signal level and the times of starting and ending it are applied sequentially to the components. CONSTITUTION:With an AND gates of three inputs 1, 2 and 3, the outputs and computed separately at the time (a), (b), (c) and the like when input signals 1, 2 and 3 rise or fall. Only at times (c) and (d) when the outputs change, the output signal and times of starting and ending the level are sent out to logical circuit components, for example, gates such as AND, NAND, OR and NOR gates, buffers and FFs. In this manner, as an output is produced only when outputs of the components change, the number of packets flowing through the input processing section - output processing section - input processing section... can be reduce to the minimum necessary and as the computation is done only when the signal changes, the frequency of data processing can be cut drastically thereby achieving a higher speed of the simulation.

Filed: 1997-07-24
Abstract: PROBLEM TO BE SOLVED: To reduce the effects due to changes in intensity of a laser and of dispersion of neighboring line by passing diffraction light of photoacoustic element, where progressing sound wave and reflected sound wave coexist, through an iodine cell and by controlling the oscillating frequency of the laser in such a manner that the phase difference of a specified signal wave between after passing the cell and before passing the cell becomes constant. SOLUTION: Light 20 of a laser 1 is incident to a photoacoustic element 3 having a progressing sound wave and a reflected sound wave driven by a sound wave exciting power source 11 having a frequency of fa. A two-cycle light 21 with a difference of 2 fa diffracted by this element is diffracted again by a photoacoustic element 4, having only the progressing sound wave driven by the same fa. Two-cycle light 22 and non-diffracted transmitting light 23 pass through a iodine absorption cell 5 and then detected by 2 light detectors 6, 7, and the detected electric signals are mixed with the output of a local oscillator 12 having the frequency of 2fa+Δf together with previous 2 signals in mixers 8, 9.  Then they become 2 sets of low frequency signals with a difference cycle of Δf and drive an oscillating frequency tuning section 2 of the laser 1 so as to make the phase difference constant.

Abstract: PROBLEM TO BE SOLVED: To conduct excellent shade correction without increasing the capacity of a memory by comparing read white board data with a prescribed value and switching the range (gain range) of a variable power rate of the white board data read by a read section based on the comparison result. SOLUTION: The gain range GR1 where the width of a variable power rate is switched from one time to two times and a gain range GR2 where a width of the variable power rate is switched from one time to four times are used. A CPU 2209 sets the gain range GR1 usually and allows a comparator circuit 3010 to compare the reference value T with white reference data a (n) at each pixel every time optical scanning of each color is executed. Then the CPU 2209 controls selectors 3003, 3006 so that the gain range GR1 set at present is not switched when the comparison result by the comparator circuit 3010 is in the range correctable for shading by the gain range GR1 and the range GRI is switched to the gain range GR2 when the result exceeds a shade correction available range by the gain range GR1.

Title: Drying device
Inventor: MORIYA YOSHIFUMI
IPC: B01D53/26
Filed: 1990-09-03
Abstract: PURPOSE:To permit a rapid move to a dehumidifying process in order to achieve an efficient drying by using an adsorbing material partially in a drying device and providing a post purge process after completion of regeneration process. CONSTITUTION:In order to bring the supplied air back into a drying chamber 7 after dehumidifying in a dehumidifying part 1, the interior temp. of the drying chamber 7 is reduced to a low value extremely rapidly. At this time, a moisture absorbing sheet 8 attached to the inner wall of the drying chamber 7 releases the moisture reserved up to this point, since the drying chamber 7 is in a low humidity condition. At this point, the dehumidifying process is finished and the air is moved on to a regeneration process. After the regeneration process, since an air blower is in operation even if a heat supply machine is stopped, heat can be removed from the dehumidifying part 1 and released into the air and the temp. of the dehumidifying part 1 is reduced rapidly to so a low value as to be able to absorb moisture from the air in the dry chamber 7. At this time, a damper part 5 constitutes an air flow passage in communication with a drying space and the air flow in the drying space induced by an air blower 3 is supplied into the dehumidifying part 1, thereby making the entry into the dehumidifying process possible.
